Ok, don't laugh, I'm a newbie :-(.  I have written this program for school and I don't know where or what to do next, or if I need to throw this away and start over.  Can anyone help me?

#include <iostream>

using std::cout;
using std::cin;
using std::endl;

#include <iomanip>

using std::setw;
using std::setprecision;

double wages(  ); // function wages prototype
int display(  ); // function display prototype

int main()
{

int salesPerson;
double salesPerWk;
int salary;
int count;

int range[ 11 ] = { 300, 400, 500, 600, 700, 800, 900, 1000 };

for ( int i = 0; i < 11; i++ ) {
      count = range[i] + 1;

// call wage function
      cout << "Enter salesperson sales per week:  ";
      cin >> salary;

// call display function
      cout << "Total sales in $200 - $299 range are:   ";


} //end main


// define wages function
double wages(salary);

while (salesPerson <= 9 ) {
      salary = salesPerWk * .09 + 200;
      salesPerson = salesPerson + 1;
}

// define display function
int display;
{
if ( salary < range[300] )
      cout << "a";
      else if ( salary < range[400] )
            cout << "b";
            else if ( salary < range[500] )
                  cout << "c";
                  else if ( salary < range[600] )
                        cout << "d";
                        else if ( salary < range[700] )
                              cout << "e";
                              else if ( salary < range[800] )
                                    cout << "f";
                                    else if ( salary < range[900] )
                                          cout << "g";
                                          else if ( salary < range[1000])
                                                cout << "h";

      return 0;
} // end if

OK, you had a few syntactical and logical errors, the following compiles:

#include <iostream>

using std::cout;
using std::cin;
using std::endl;

#include <iomanip>

using std::setw;
using std::setprecision;

double wages(  ); // function wages prototype
int display(  ); // function display prototype

int range[ 11 ] = { 300, 400, 500, 600, 700, 800, 900, 1000 };

int salesPerson;
double salesPerWk;
int salary;
int count;

int main()
{


for ( int i = 0; i < 11; i++ ) {
    count = range[i] + 1;

// call wage function
    cout << "Enter salesperson sales per week:  ";
    cin >> salary;

// call display function
    cout << "Total sales in $200 - $299 range are:   ";

   }

return 0;
} //end main


// define wages function
double wages()
{

while (salesPerson <= 9 ) {
    salary = salesPerWk * .09 + 200;
    salesPerson = salesPerson + 1;
  }

  return salary;
}

// define display function
int display ()
{
if ( salary < range[0] )
    cout << "a";
    else if ( salary < range[1] )
         cout << "b";
         else if ( salary < range[2] )
              cout << "c";
              else if ( salary < range[3] )
                   cout << "d";
                   else if ( salary < range[4] )
                        cout << "e";
                        else if ( salary < range[5] )
                             cout << "f";
                             else if ( salary < range[6] )
                                  cout << "g";
                                  else if ( salary < range[7])
                                       cout << "h";

    return 0;
} // end if

1st of all, there were problems with the synatx regarding e.g.

double wages (); // semicolon incorrect when code follows

Then, the variables you declared in 'main()' need to be "global" to be accessible by the two other functions.

Ok, I'll try this.  But, does it look like I actually have any clue as to how C++ works?

Ok, don't answer that!  One more question:  how do I get the array values to fall into the display function?

Th eproblem with the array mainly is that by using an index 'n' into them, you're accessing the 'n'th element, so using '300' with an array of 11 elments will not work. I'd suggest to use


#define SALARY_300 0
#define SALARY_400 1
#define SALARY_500 2
#define SALARY_600 3
#define SALARY_700 4
#define SALARY_800 5
#define SALARY_900 6
#define SALARY_1000 7

// define display function
int display ()
{
if ( salary < range[SALARY_300] )
    cout << "a";
    else if ( salary < range[SALARY_400] )
         cout << "b";
         else if ( salary < range[SALARY_500] )
              cout << "c";
              else if ( salary < range[SALARY_600] )
                   cout << "d";
                   else if ( salary < range[SALARY_700] )
                        cout << "e";
                        else if ( salary < range[SALARY_800] )
                             cout << "f";
                             else if ( salary < range[SALARY_900] )
                                  cout << "g";
                                  else if ( salary < range[SALARY_1000])
                                       cout << "h";

    return 0;
}

to map the entries to their ranges by name.

BTW, an advanced step would be using a loop, e.g.

int display ()
{
char alpha[] = "abcdefgh";
int i;
for ( i = SALARY_300; i <= SALARY_1000; ++i)
{
  if ( salary < range[i]) cout << alpha[i];
}
    return 0;
}

Oops, seems that I have again been a tad bit slow when typing :o)
